scsi: ufs: core: Make DMA mask configuration more flexible
[ Upstream commit 78bc671bd1501e2f6c571e063301a4fdc5db53b2 ]
Replace UFSHCD_QUIRK_BROKEN_64BIT_ADDRESS with
ufs_hba_variant_ops::set_dma_mask. Update the Renesas driver
accordingly. This patch enables supporting other configurations than
32-bit or 64-bit DMA addresses, e.g. 36-bit DMA addresses.
